Need to keep things pumping late into the night? But maybe without overwhelming your pleasure centers with stimulants and delaying an eventual blissful slide into sleep? Caffeine’s out, but these energy-boosting supplements, which don’t stimulate the central nervous system, aren’t.
Citrulline Malate Formed by bonding the amino acid citrulline to malic acid, citrulline malate decreases ammonia levels in your body, reducing fatigue. This is particularly beneficial during periods of intense activity such as exercise or periods of stress. Citrulline malate also helps convert lactic acid to energy, reducing and delaying muscle fatigue. Try 1 to 3 grams twice a day, one dose before breakfast and the other before your workouts.
Green-Tea Extract While green tea itself is great for boosting energy, it also comes with a moderate dose of caffeine. Green-tea extract, on the other hand, offers enhanced energy without the added buzz. The active ingredients are catechins, antioxidants that help boost norepinephrine levels, which increases metabolic and heart rates. Take up to three 500-milligram doses throughout the day, including in the evening before jumping in the sack.
Leucine One of the branched-chain amino acids, leucine can be used by muscles for fuel, helping to power you through intense workouts or other physical activities. It also spares muscle tissue, pulling body fat from storage for fuel. Take 3 to 5 grams of leucine or BCAAs before workouts and before bedtime, whether your goal is a good night’s sleep or a strenuous romp with your partner.
